Résumé
Objective To investigate principles of acupoint selection for the ancient acupuncture and moxibustion treatment of facial paralysis.Methods The ancient literature about acupuncture and moxibustion was collected and reviewed from the pre-Qin period to the late Qing Dynasty. According to the data selection criteria, acupuncture and moxibustion prescriptions of facial paralysis were collected and input into an ancient acupuncture and moxibustion prescription database. By use of frequency analysis and factor analysis, the principles of acupoint selection were obtained.ResultsTotally 257 prescriptions were collected which involve 74 acupoints. Through frequency analysis, 19 acupoints were obtained whose frequencies were equal or greater than 9, such as Dicang (ST 4), Jiache (ST 6), Tinghui (GB 2), Shuigou (GV 26), Hegu (LI 4), etc. Through factor analysis of acupoint variables, 6 common factors were obtained.Conclusion Based on analysis of the common factors, the principles of acupoint selection are summarized which were according to meridian, part and etiology for the ancient acupuncture treatment of facial paralysis. The results could provide a reference for clinical acupuncture and moxibustion treatment. It is feasible that factor analysis was applied to study principles of acupoint selection for acupuncture and moxibustion prescriptions.

Objective To analyze the levels of high density lipoprotein ( HDL) and low density lipoprotein ( LDL) among the staff in a college .Methods Fasting serum samples were collected from 2 234 paticipants .The lev-els of HDL and LDL in different sex and ages were estimated .Results The average value and abnormal rate of LDL in males were 3.20mmol/L and 49.1%,respectively.The average value of LDL in males was higher than normal val-ue.The average value and abnormal rate of LDL in females were 3.03mmol/L and 42.3%,respectively.The value of LDL in females who less than 54 years old was lower than that in males of the same age ( t=5.33,10.56,all P<0.01).Conclusion The abnormal rate of LDL had significant increase and the level in males was higher than that in females.The health education is necessary to prevent and control the abnormal level of LDL .

Objective To compare the bacterial community profiles present in periodontium and root canals of the same tooth diagnosed as combined periodontal-endodontic lesions by using denaturing gradient gel electrophoresis (DGGE).Methods Samples were collected from 13 extracted teeth with advanced periodontitis,endodontic samples from root tip 1/3 root canal,and periodontal samples from the corresponding neighboring periodontium.Genomic DNA was collected for the following universal bacterial primersPCR.The PCR products were then loaded on the DGGE gels to gain separate bands.The typical DGGE bands were excised,PCR-cloned and sequenced.Results The number of bands,which was indicative of the number of bacterial species,was compared intra-group (periodontal and pulpal specimen from the same tooth).The difference was statistically significant (P＜0.01),but there was no positive correlation between them.The similarity (Dice Coefficient) between them was 13.1％-62.5％.Taxa identified through BLAST (≥98％ identity) were Campylobacter,Fusobacterium,Neisseria,et al in the periodontium,and Mogibacterium,Corynebacterium,Actinomyces,et al in the root canals.Conclusion Common bacteria existed between them,but not all of the periodontal bacteria would appear in neighboring root canal; and the bacteria in the root canal are not completely from neighboring periodontal tissue.The original bacteria in the root canals may resuscitate and enrich the bacterial community.In combined periodontal-endodontic lesions (periodontal source),it is probable that new species existed to be confirmed either in the periodontium or in the root canal.
